I'd be cautious in who you end up meeting from any site.
People can be nasty animals (not pointing any finger). There is a slight chance that you could meet the law.
Or worse, someone who wants to see where you grow, or where your friend grows. I have friends who grew outdoors and got ripped off by just one other person knowing.
Scumbags came when the plants were just about 3 weeks into flower. Pulled all the plants up, stole some and destroyed the others. I'm talking about 80-100 plants here.

I would advise not to get into this meeting habit. I wouldn't even meet someone to hand them a seed or two. It's just too risky, if you don't want trouble at your door.
Go to Dublin, buy what you need and get the train/bus/ or drive your car home to Wicklow.

Growing yourself is the best way to keep your head down and avoid getting in trouble with the law and getting to know shady criminal gang members.
If you have 1,000 Euro to spare and an attic or a spare room you will never go short again. An attic is the best option.
Intake fresh air from on bedroom and release into a different bedroom. Have a nice sized tent in the attic. In winter the warm air from the rooms will keep the tent temp up too. I grow with LED which runs cool so the tent needs heat in winter.

I have a grow that you can see here: Led Logger

So that's my two pence on this matter. I hope it makes some sense to you.

Take care and stay safe. (Stranger Danger)
